Prepended Pdt to the Expand libraries and classes in the PDT extension, and prepended MPdt to the Expand libraries and classes in the MPDT extension, so that both can be used in the same compilation unit (1.5.1)

Added option to PDT Replace for compiling a strongly-regular RTN into a bounded-stack PDT (1.5.1)

farextract now allows one to specify a list of comma-separated keys, including key ranges (1.3.3)

Fixed bug in PDT replace that could cause close paren IDs to collide with open paren IDs (1.3.4)

OpenFst - Release 1.2

Added lookahead matching and filtering for faster composition

Added EditFst for mutation of o.w. immutable FSTs

Added script sub-namespace defining type FstClass - a non-templated Fst<Arc> to hold the arc template type internally. This and FST operations on it allow easier I/O and scripting at the cost of some runtime dispatching.
